226 THIRTIETH REPORT ON THE STATE MUSEUM. 



large, uniformly dark, subsemicirctilar in outline, while in 

 populata it is reduced to nearly a blackish oblique streak, 

 behind which is the uniform shade of the terminal margin. 



In color, Paclcardata is of a pale yellow, with great contrast 

 between the ground color and the interior bordering of the 

 two bands : populata is more uniform in its darker ochra- 

 ceous shading, with the darker yellow tending to a diffu- 

 sion over the whole of the mesial band. Our species is also 

 of a larger size than the European, two examples measuring 

 respectively 1.50 in. and 1.38 in., while the examples of the 

 latter before me are but 1.25 in. in expanse. 



Material under observation : One male of C. PacTcardata, 

 from Collection of Otto von Meske, made at Sharon Springs, 

 N. Y., August 14, 1875 ; one male from Collection of W. W. 

 Hill, taken in Lewis county, N. Y., July 27, 1876. Of 

 C. populata, two males and one female received from Dr. 

 Speyer, of Germany, from Collections of Mr. von Meske, 

 Mr. Hill and my own. 9 



C. populata is very well represented on PL 22, fig. 590 of 

 Wood' s Index Entomologicus, in its characteristic shape of 

 wings and disposition of bands. Its habitat and apparition 

 are there given as ' 4 common in the north of England and in 

 Scotland, in July." It is referred by Stephens to the 

 genus ELECTRA.
